' T aZZ whom 2713 may concern:

Be it known that 1, Jenna H. FINCH, 3n,

a citizen of the United States, residing at Quincy, in the county of Norfolk and State of Massachusetts, have invented certain new anr'iuseful Improvements in Gasolene-Filters; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to, the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in gasolenc filters or purifiers and the object in View is to produce a simple and ellicient device of this nature having various details of construction and combinations and arrangements of parts which \Ylll be hereinafter fullydescribed, shown in the accompanying drawings and then specifically defined in the appended claims.

1 illustrate my invention. inthe accompanying drawings, in which Figure l is a central longitudinal sectional view through the filter, and Fig. 2 is a sectional view on-line 22 of Fig. 1.

' Reference now being had to the details of the drawings by letter, A designates a cylinder having a conical shaped projection B extending within the cylinder at one end and which is rovided with a duct D leading through to end of the cylinder and to which a pipe, not shown, is adapted to be connected. Said end ll is provided with a transverse duct E which communicates-with a valved stop cock 1*, while its other end communicates with a pipe N, open upon its under side. A plug, designated by letter O,

. has its inner end 0 conical shape and has a hole the walls of which are threaded for the reception of the threaded end of the pin B which is integral with the opposite end B. A suitable gasket R is interposed be.- tween the flange of the plug 0 and the annular flange R which projects from the inner wall of the cylinder. A strainer, designated by letter S and made preferablyfof cham0is,- has its endstclescoping therein and a coiled spring W is inserted within said flange and telescopes over the rings Q which tend to hold the inwardly extending ends of the strainer against the coiled spring. Said spring tends to hold the chamois covering, holding the strainer taut, the spring having hearings against the inclined end of the cylinder and the tapering part of the plug.

A socket L is formed in the wall of the gasket and to which a pipe is adapted to be connected and from which socket a duct ll leadsinto the interior oi the cylinder and through which the liquid'to be filtered is adapted to be passed.

The operation of my device will. be reacily understood and is as follows :The gasolene or other liquid to be filtered passes through the duct L into the interior of the cylinder. .Any Water which may be mixed with the gasolene will settle to the bottom of the cylinder and pass through the pipe N where it may be blown oil by opening the stop cook. The pressure upon the oil will cause the same to pass througl'i the chamois strainer and any impurities will fall'to the hottoin f the tank and be discharged with the water, while the filtered gasolcne will pass through the duct D and be piped to any suitable location.

What I claim to be new is 1. A. gasolene filter comprising a cylinder, an integral pin projecting from the inner end and having a threaded circumference, said end provided with an exit oil duct, a plug fitted within the opposite end of the cylinder and having a threaded opening for the reception of said pin, coilcd spring about said pin, a strainer within the cylindcr and held by said spring against the inner end of the cylinder and said plug, said cylinder having in its lower portion a pipe which is open upon its. under edge, and a duct leading through the wall of the cylin within one end ofthe cylinder and having a threaded hole for the reception of said pin, a cylindrical shaped chamois filter having intu'rned ends, n coiled spring mounted wltlnn sand filter, lungs wltlnn the lntul'ned ends and adapted to hold the same agalnst said spring, the latter bearing against the inwardly projecting end of the eylindenand said plug, a horizontally disposed pipe within the cylinder at the lower end'thereof and open upon its under edge, and avalved duct leading through one end of (he Cylinder and eon'nnunicnting with said In testimony here 'slgnntnre 1n presence Witnesses:
